Page 4: Executive Summary
To supplement the growth in iSCSI SANs, Dell has introduced an iSCSI-to-SAS bridge card for the TL-series of tape libraries (Dell PowerVault TL2000 & TL4000). This offering allows a customer to directly attach a tape backup target to their iSCSI 1Gb Ethernet SAN with little to no degradation in transfer speed, 90 MB/s in most cases. -

SECTION 3 iSCSI SAN SOLUTIONS To complement the Dell PowerVault MD3000i and Dell EqualLogic & EMC line of iSCSI inter- face disk storage systems, Dell has introduced an iSCSI-to-SAS Bridge Card for the Dell PowerVault TL2000 & TL4000 tape libraries. This card, when inserted into a TL-Series tape library, acts as an iSCSI target and provides SAS connectivity for LTO4, LTO4HH and LTO3HH tape drives. -

Page 7: Network Settings
iSCSI for TL-Series Tape Libraries One drawback to Microsoft’s iSCSI Initiator is that it does use the server cycles to create the iSCSI packets. This, in combination with other processor-intensive operations (like back-up jobs), can reduce the performance and throughput of the server and associated back-up jobs. Alternatives would include the use of a HW iSCSI HBA or other off-load engine. -

iSCSI for TL-Series Tape Libraries Use of Jumbo Frames – Although somewhat controversial, in a clean network, jumbo frames can significantly improve the performance of back-up jobs. However, if the network is subject to dropping packets (e.g., high traffic), the performance could degrade due to resending the larger packets. -
Page 9: Figure 10 : Powerconnect
iSCSI for TL-Series Tape Libraries For Jumbo frames to function properly, the entire path between the back-up server to the stor- age target needs to enable jumbo frames. Assuming a PowerConnect 5448 switch, this is done as follows: Figure 10 : PowerConnect 5448 Select Advanced Settings and then General Settings. -

SECTION 6 CONFIGURING AN MD3000i Assuming a Dell PowerVault MD3000i, an iSCS disk array, is connect to the example network, the initial configuration would require physically installing & powering on the unit and then in- stalling and running Modular Disk Storage Manager (MDSM) on the host computer. After in- stallation of MDSM has been completed on the host computer, the disk array must be discov- ered by the host. -

iSCSI for TL-Series Tape Libraries Figure 15 : Configure iSCSI Settings Figure 16 : Configure Host Ports Note: If Jumbo Frames are enabled, they must be enabled for all devices across the network (including the host, target, and any switches or routers in between). Jumbo frame sizes will allow for greater packet payloads and lower overhead traffic, resulting in likely performance increases. -

iSCSI for TL-Series Tape Libraries Windows Servers it is recommended that you run the Backup Exec Environment Check on the system which is planned to contain the Backup Exec installation. The Backup Exec Environment Check is included with the installation media. The Environment Check analyzes the computer to make sure that the installation process can complete. -

Select any additional features as required and continue with the installation. - Page 14 Implementing the Strategy within Backup Exec A Dell PowerVault TL2000 can accommodate up to 2 tape drives (2U) and a TL4000 can ac- commodate up to 4 tape drives (4U) and backup jobs can be created to utilize each drive in the tape library.
